PPMT20V3

Shanghai Prisemi Elec · MOSFETs · SOT-23

PPMT20V3 from Shanghai Prisemi Elec, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate terminal; the absolute maximum gate-source voltage is ±8 V and the gate threshold voltage is -0.45 V to -0.9 V.
2 S passive Source terminal of the P-channel MOSFET, serving as the reference for VGS; the datasheet gives no source-specific rating.
3 D passive Drain terminal; the absolute maximum drain-source voltage is -20 V and the continuous drain current is -2.8 A.

CAD (KiCad official)

  • Symbol: PPMT20V3
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ppmt20v3-etched.step / ppmt20v3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ppmt20v3.step / ppmt20v3.glb are the bare package body.
